DAVID J. HAUSS, OF AURORA, INDIANA.

MUSIC-PLAYER.

Application filed October 23, 1909.

To all whom it may concern:

Be it known that I, DAVID J. IIaUss, a citizen of the United States,residing at Aurora, in the county of Dear-born and State of Indiana,have mvented certain new and useful Improvements in Music-Players, ofwhich the following is a specification.

My invention relates to improvements in electrically actuated musicplayers. One of its objects is to provide improved means to feed themusic sheet, to regulate the speed with which the sheet is fed, to stopand start the feed, and to feed the sheet backward at an increased rate.

Another object is to provide improved mechanism to conveniently controlthe various movements of the sheet.

It further consists in certain details of form, combination andarrangement, all of which will be more fully set forth in thedescription of the accompanying drawings in which:

Figure 1 is a front elevation of a piano with my improvements attachedthereto. Fig. 2 is a diagram of the controller mechanism and electricalconnections to said controller and motor. Fig. 3 is a side elevation ofthe controller. Fig. 4 is a detail of a modification of Fig. Fig. 5 is asectional detail of the rewinding clutch mechanism. Fig. 6 is a similarview of a modification. Fig. 7 is a sectional detail. of the clutch shifti n g mech anism.

In the accompanying drawings A repre sents the piano casing.

B represents an electric motor.

U represents a shaft which is clutched to and adapted to drive the sheetfeeding roll. from which the sheet is being fed during the act ofproducing the music.

I) represents a shaft which carries and is adapted to drive the roll Dwhich. receives the sheet during the act of producing the music.

I) represents a shaft which ismounted concentrically with the shaft 1)and driven slowly from the motor B by means of a worm I) on the motorshaft, a worm wheel Z) 011 the shaft 6 and thence by beveled gear 6 onshaft and beveled gear I) on shaft D. Two spur gears (Z (Z are mountedside by side on the adjacent ends of shafts I) D and motion istransmitted from gear (Z' to gear (Z by means of a pinion (l having aface wide enough to mesh with both gears Specification of LettersPatent.

cl and d. The pinion 61 is carried on pivoted frame (Z and is adapted tobe shifted into and out of engagement with gears d d by means of a leverd having inclined projections d to shift said frame. Said lever alsopreferably at the same time serves to open and close a switch 6Z6controlling the music key circuits.

The opposite end of the motor shaft carries a friction gear 0 which isengaged by a friction gear 0 on a shaft 0 journaled in frame d Shaft 0carries a sprocket-wheel 0 which by means of a sprocket chain 0* andsprocket wheel 0 on shaft G tends to drive shaft G in a directionopposite to that which it would be driven by the rotation of shaft D.I/Vhen the gears (Z (Z (Z are in mesh the shaft D rotates the musicrolls C 2 in the direction to feed the sheet from roll C to roll D andfriction gear 0 is out of engagement with friction gear 0. lVhen thegear (l is thrown out of mesh with gears (Z (5 the friction gear 0 isshifted into engagement with friction gear 0 and serves to rotate themusic rolls at an increased speed to transfer the sheet from roll D toroll 0.

In the modification Fig. 7 the motor is provided with a pinion C inplace of a friction gear and a spur gear 0 carried by frame d is shiftedinto mesh with pinion 0 and in turn drives spur gear 0" on shaft C torewind the sheet on roll C. If desired a duplicate set of gears 0! cl (Zmay be employed to drive shaft C to rewind the sheet.

The motor is preferably of the direct current type comprising a magneticfield energized by a field coil H, an armature it, a commutator 7a and aplurality of contact brushes iffy.

The motor is controlled by means of a controller preferably comprisingtwo sections J J. The section J is pivotally supported by means of agrooved collar of insulating material which rests between the forkedarms of a bracket in which is rigidly supported upon the controllerblock or base K. The section J is telescopically adjustable within thebore of section J and is splined and prevented from turning within thebore of section J or being completely withdrawn therefrom by a screw 7".The forward or projecting end of section J is downwardly turned tofacilitate holding and manipulation of the controller, said sectionbeing preferably insulated from section J.

L represent buttons arranged upon the controller block K concentricallyabout the center L, and upon opposite sides thereof. The block K is ofinsulating material and has pivoted thereto at the center L a cross baror switch lever M the opposite ends of which are adapted to contact withdiametrically opposite buttons L. Sections of resistance wire Z serve toconnect in series adjacent buttons L upon opposite sides of the block K.The bar M has also connected thereto and projecting at substantiallyright angles a forked arm M, the forked end of which engages oppositesides of a sleeve m of insulating material carried by the section J ofthe controller.

N N represent contact plates carried by the block K and adapted to bealternately or selectively engaged by the contacts or brushes n acarried by the controller section J. A spring 71 serves to normally holdthe controller in position to make contact between the plate N and brusha.

A line 0 connects the lower button L of the right hand series with thecontact brush If of the motor. A line P connects the upper button L ofthe left hand series with the brushes 12- it. A line B connects theplate N with lead screw 1 of the motor, which is in turn connected byline r with one end of the field coil H. Plate N is connected by line Swith the lead screw T of the motor which in turn is connected by line 6'with the opposite end of the coil H, and by line It with the contactbrush [L of the motor.

U U represent the line wires.

When not in operation the controller section J is telescoped withinsection J so as to be out of the way beneath the key board. lVhen inoperation the section J is drawn forward so that its forward endprojects slightly beyond the key board. The sheet rolls being adjustedto position, and the main line switch V closed to supply current to themotor, and brush a and plate N being in contact, the motor will start torotate and slowly feed the sheet from roll 0' to roll D The speed of themotor can be varied within the limits required by moving the controllerlever J to the right or left, a movement to the right increasing and tothe left decreasing the motor speed. hen it is desired to stop the motorthe controller lever J is turned upon its axis to break the contact atn, N, and to make contact at n N which. serves to convert the armaturefrom a motor to a generator with theresistance Z in circuit and aseparately excited field, which acts as a brake upon the armature andstops its rotation instantly. After the sheet has been fed from roll 0to D the lever 6Z is shifted to throw gear (Z out of mesh with gear (Z,whereupon the friction gears c 0 drive the roll C at increased speed inthe reverse direction to return the sheet to roll G.

In the modification Fig. 4C the plates 2, 3 corresponding to the platesN N of Fig. 3 are located above and below the controller lever 4-, andto stop the motor the controller lever is lifted vertically to breakcontact between the brush 5 and plate 2, and to make contact between thebrush (3 and plate The mechanism herein illustrated and described iscapable of considerable modification without departing from theprinciple of my invention.
